In the manufacturing process, the metal powder and diamond grit mixture is hot pressed at high temperatures to form a solid metal alloy (called the bond or matrix) in which the diamond grit is retained.
The segment or rim is slightly wider than the blade core. This allows the cutting edge to penetrate through the material while protecting the steel body.
The application of bond (or Matrix)
- Typically the following rule applies :
- For hard materials : use soft bonds.
- For soft materials : use hard bonds.Example : Limestone is soft and abrasive therefore we would use a hard bonded blade. Reinforced concrete with river pebble aggregate is hard therefore we would use a soft bonded blade.
Means that the compilation of metals when sintered together forms a segment of approximately 105 to 120 HRB (hardness) and is very resistant to the soft abrasive materials being sawn, thus releasing diamond at the appropriate rate.
Hard bonds typically consist of the following metal powders – cobalt, iron, tungsten carbide and are grey to dark grey in colour.
Means that the compilation of metals when sintered together forms a segment of approximately 90 to 105 HRB (hardness) and allows the segment to wear quicker thus retaining diamond on the cutting surface.
Soft bonds typically consist of the following metal powders - copper, bronze and cobalt, and are generally bronze to light silver in colour. Here are the cutting results of our diamond segments by years of accumulation,Artificial stone: 90000-110000m²
